Restrictions and Cautions
When configuring the Switch 4500G, be sure that you are aware of these restrictions and cautions:
1) VLAN ACLs cannot take effect on QinQ-enabled ports because of implementation limitations.
2) When the configuration of port isolation conflicts with the redirect action of QoS, the port isolationconfiguration overrides. For example, assume ports g1/0/1 and g1/0/2 belong to a port isolation
group and the QoS policy applied on g1/0/1 contains a traffic behavior to redirect traffic received
on g1/0/1 to g1/0/2. When receiving traffic matching the QoS policy, port g1/0/1 will not redirect it
to port g1/0/2, because both ports are members of a port isolation group, which prevents them
from forwarding traffic to each other.
3) The broadcast/multicast/unknown unicast suppression threshold configured as a percentage of
the total bandwidth in port view is accurate only for 64-byte packets. This is because the chip
supports only broadcast suppression by PPS, and the system converts the percentage into PPS
per 64 bytes. Thus, you are recommended to configure storm suppression by PPS.
4) The virtual cable test (VCT) function will fail if the connected peer port works at 100 Mbps in
forced mode.

Software Upgrading
The device software can be upgraded through console port, TFTP, and FTP.
Remote Upgrading through CLI
You may upgrade the application and Boot ROM program of a device remotely through command line
interface (CLI). To this end, telnet to the device from a computer (at 10.10.110.1) running FTP server
first; and then get the application and Boot ROM program, switch.app and switch.btm for example,
from the FTP server as follows:

Note that if you do not have enough Flash space, upgrade the Boot ROM program first, and then FTP
the application to the device.
The following sections introduce some approaches to local upgrading.
